It seems that technology is gradually catching up with the mythological & mystical ideas of the Crystal_ball & the magic_mirror. The perception of reality isn't as simple as black & white because there is a vast spectrum of data to research & compare. http://harrypotter.wikia.com/wiki/Crystal-gazing
Metaphorically, each galaxy is like its own BD or DVD containing an interactive recording & projection of space & time. Each universe is like its own disc on a cosmic hard drive.
The concept of the crystal ball & the magic mirror has lead to 3D or holographic projection, the flat screen smart TV, pocket phones & the iPad. They all have become variations of computer development. But how did people before the time of modern electronics & computers ever get such ideas? Enter the cosmic-computer-hypothesis.
